The NTW-20 is an anti-material rifle developed by Denel Land Systems in the 1990s. Intended to be deployed against targets like parked aircraft, telecommunication masts and other targets using a range of specialized ammunition.

The NTW-20 comes with a muzzle brake and a buffered slide in the reciever which effectively absorbs recoil and a rare feature allowing changing of caliber without complete disassembly. Switching between calibers is done by switching the bolt, barrel, sighting gear and magazine.

The NTW-20 is currently accepted into service with the South African National Defense Force.
